Singing duo Bill and Kate Isles headline the next show in the Point Richmond Acoustic concert series at 8 p.m. Friday at the historic First United Methodist Church, 201 Martina Ave. in Point Richmond.

The singer/songwriter pair are popular acoustic performers in the Midwest “and have received national and international attention with comparisons to heartland songwriters like Willie Nelson and Woody Guthrie.”

Opening the show will be special guests The Henriettas, (Nell Robinson and Cary Sheldon) who bring their style of 1930s Americana music to the stage.

In addition to evacuating 10 neighboring homes, deputies restricted pedestrian and vehicle traffic in the area while the sheriff's office bomb squad "safely disposed" of the explosives, officials said.
